Generalised Short-Duration Method
The Generalised Short-Duration Method is appropriate for durations up to 6 hours, suitable for small catchments such as those of reservoirs and tailings dams anywhere in Australia. Formerly known as the 'Bulletin 51 Method', it was revised and republished as Bulletin 53 under the title 'The Estimation of Probable Maximum Precipitation in Australia: Generalised Short-Duration Method' (BoM, 1994, amended December 1996 and January 2003).
The method and data from Bulletin 53 along with amendments such as those issued in December 1996 and January 2003, have been incorporated into a new downloadable document, 'The Estimation or Probable Precipitation in Australia: Generalised Short-Duration Method' (BoM, 2003), which supersedes Bulletin 53.
GSDM PMP estimates may now be obtained by following the procedures in The Estimation of Probable Precipitation in Australia: Generalised Short-Duration Method (BoM, 2003). This new GSDM guidebook is readily available by downloading as an Adobe Acrobat PDF document.
Bulletin 53 is now withdrawn.
